Alrighty, well first things first.
Moved your topic to the proper forum.
Don't forget the "shift" key.
Are you asking about your Zaku or your Gundam? The post seems to be about your new Zaku II kit, but the thread askas about your Gundam... I suppose we could help either way.
First, it'd be good to know what techniques you already used on your Gundam kit. There are different levels of work you could do on your kit depending on your level of experience with kits, so knowing what you've already done will help us know what kinds of things to suggest.
